STRAIN'ER.

Application filed. October 15, 1921. Serial No. 507,963.

To all whom it may concern:

Be it known that I, CHARLES H. S'runcrs, a citizen of 'the United States, and a resident of Granville, in the county of Putnam and State of -Illinois, have invented a new and Improved Strainer, of which the following is a full, clear, and exact description.

This invention relates to improvements in strainers, particularly to a strainer for use With thegasoline tank of an automobile, an object of the invent-ion being to provide meansfor directly associating the strainer with thetank so that gasoline is strained before it enters the pipe line.

A further object is to provide a strainer of this type, which can be very easily cleaned, which will be simple and practical in construction, eflicient in use, and which can be manufactlu'ed with economy.

-\Vith these and other objects in view, the invention consists in certain novel features of construction' and combinations and arrangements of parts as-Will be more fully hereinafter described and pointed out in claims.

In the accompanying drawings:

Figure 1 is a view in longitudinal section through my improved strainer;

Figure 2 is a sectional view on the line 22 of Figure 1; and O 1 Figure 3 is a perspective view of the strainer frame 1 With the strainer supported therein.

Referring in detail to the drawings, I have used the reference numeral 1 to designate a conventional form of cylindrical gasoline tank, supported upon the rear end of an automobile (not shown). A short externally threaded sleeve 2 is screwed into an opening 3 in the bottom of the tank.

My improved strainer in ludes a cylindrical casing. such as 4 having an inlet port 5 in its top and an outlet port 6 in its side. A bushing such as 7 is screwed into the inlet end of the tank and the bushing 7 and sleeve 2 are coupled by a casting such as 8, which screws onto the sleeve and into which the bushing is screwed until the lower end .of the casting fits tightly against; the top mounting for any a proved'type of rotary plug valve 10 contro ling the flow from the tank to the casing. This valve is closed when it becomes necessary to clean the casing.

Thecylindrical casing; is open at one end to permit the insertion of a strainer carrying frame 11. This frame is a cylindrical skeleton structure including end rings 12, connected by longitudinal integral slats 13.. The open mouth of a baglike strainer 14-. is supported between two of the slats 13 and I provide for the proper positioning of the mouth of the bag under the inlet port by forming a keyway 15 in the casing in which a key 16 carried by one of the slats 13 rides. The skeleton frame 11 cannot be entirely inserted into the casing unless the key 16 enters the groove 15 so that the proper positioning of the baglike strainer 14 is assured. After the frame 11 has been inserted into the casing, the open screw threaded end thereof is closed by a plug 17, this plug preferably being formed with an integral handle 18 tofacilitate its insertion into and removal from the casing.

The operation of the device will be readily understood. The gasoline flowing from the tank passes through the. strainer 14 and out through the outlet port 6. This port is located at an appreciable distance above the eral form and arrangement of the parts described without departing from the invention and hence I do not wish to limit myself to the precise details of construction, but shall consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. A device of the characterdescribed, I

including a casing having a horizontally elongated chamber, an inlet port leading to the roof of said chamber intermediate the chamber ends, and. an outletport from said chamber at a point below the inlet port; a cup-like strainer; an elongated skeleton frame on which the strainer is mounted at its rim to extend the body of the strainer within the frame transversely thereof intermediate its ends; and coacting means carried by the frame and the casing whereby the frame may be endwisely completely seated in the chamber only when the rim of the strainer lies in a substantially horizontal plane 2. A device of the character described, including a casing having a horizontally elongated cl iaml'oer an inlet port leading to' the roof of said chamber intermediate the chamber ends, and an outlet port from said ehber at a 'pointbelow the inlet port; a

enses cup-like strainer; an elongated skeleton frame on which the strainer is mounted at its rim to extend the body of the strainer within the frame transversely thereof in termediate its ends; and coacting means carried by the frame and the casing whereby the frame may be endwisely eompletely seated in the chamber only when the rim of the strainer lies in a substantially horizontal plane; the casing carrying a removable cap constituting one end wall or said chamber, the other end wall thereof being closed; the parts being so shaped and arranged that the cap is permitted fell closingonly when the strainer rim is in said plane.
